"Actually, the challenge I’ve always had is being too thin, so I love that now I have a booty, and obviously I love showing my cleavage,” she tells Lucky. (Check out pics of the pop star circa 2001-2003 -- she isn't kidding about the "too thin" thing.) Now she's proud of her curves, affirming, "Hey, if you can work it and you can own it, that confidence is going to shine through."

Unfortunately, it doesn't seem like Lucky loves her as much as we do. In the cover pic, sporting trendy double denim, Christina seems to have lost an inch or two off her waistline... and more egregiously, she also appears to have gotten a vertiginous facelift. Whose eyebrows do that in real life?
